Here, each charging slot SL1 may be provided with a wireless charger (not shown) that wirelessly supplies charging power to the charging vehicle 10 parked in the corresponding slot. The charging slot SL1 may be indicated charging state of the charging vehicle 10 in one area 5. The non-charging slot SL2 refers to a space which is not provided with a separate charger, wherein the space may be used as a parking space in which the waiting vehicle 20 to be charged is temporarily parked, or to which the charged vehicle is to be moved.

The vehicle charging control apparatus 100 may communicate with the parking lot control system 200 and the user terminal 300 to transmit and receive signals.

In addition, the vehicle charging control apparatus 100 may activate an automatic moving and parking function of the vehicle parked in the charging slot SL1 or the non-charging slot SL2, and control remote parking of the activated vehicle.

Here, when an empty charging slot is detected while the vehicle is waiting in the non-charging slot SL2 of the parking lot, the vehicle charging control apparatus 100 may move the vehicle to park in the charging slot on the basis of charging slot information received from the parking lot control system 200, and control wireless charging of the vehicle parked in the charging slot SL1.

In addition, when the wireless charging of the vehicle parked in the charging slot SL1 is completed, the vehicle charging control apparatus 100 may control the charged vehicle to move and park on the basis of parking space information received from the parking lot control system 200.

The configuration of the vehicle charging control apparatus 100 will be described in more detail with reference to FIG. 2.

The vehicle charging control apparatus 100, according to an exemplary embodiment of the present disclosure, may be provided in the interior of the vehicle.

Here, the parking lot control system 200 may assign priorities to waiting vehicles in order of entry into a parking lot in operation S330.

The charging control apparatus 100 of the waiting vehicle may identify the priority of the corresponding vehicle on the basis of the information received in operation S330, in operation S340, and enter a standby mode in operation S350.

When the charging control apparatus 100 of the waiting vehicle is in the standby mode, the parking lot control system 200 may check the state of a charging vehicle parked in a charging slot to determine whether the charging vehicle is allowed to move and park in operation S360. When it is confirmed that the charging vehicle is allowed to move and park, the parking lot control system 200 may transmit, to the charging control apparatus 100 of the waiting vehicle having the highest priority, a request signal for requesting the waiting vehicle to be ready to move and park in operation S370. In operation S370, the parking lot control system 200 may check information on the charging slot which is occupied by the charging vehicle that is allowed to move and park, and transmit the charging slot information along with the request signal.

Then, the charging control apparatus 100 of the waiting vehicle may wake up the waiting vehicle from the standby mode on the basis of the signal received in operation S370, in operation S380, and generate a traveling route from the current position of the waiting vehicle to the charging slot on the basis of the charging slot information in operation S390. Here, the charging control apparatus 100 of the waiting vehicle may wait until it is requested to control the waiting vehicle to move and park by the parking lot control system 200.

When it is confirmed that the charging slot is open due to the movement of the charging vehicle parked therein in operation S400, the parking lot control system 200 may transmit, to the charging control apparatus 100 of the waiting vehicle, a request signal for requesting the charging control apparatus 100 of the waiting vehicle to control moving and parking of the waiting vehicle in operation S410.

When receiving the request signal in operation S410, the charging control apparatus 100 of the waiting vehicle may control remote parking of the waiting vehicle on the basis of the traveling route generated in operation S390, in operation S420.

In addition, when the waiting vehicle has been parked in the charging slot, the charging control apparatus 100 of the waiting vehicle may control wireless charging of the vehicle in operation S430. Here, when the wireless charging is started, the charging control apparatus 100 may transmit charging start information to the user terminal 300 through the communicator in operation S440.

FIGS. 5A through 5E illustrate a sequence of operations in moving and parking a charging vehicle and a waiting vehicle, according to an exemplary embodiment of the present disclosure.

First, as illustrated in FIG. 5A, when the charging of a first vehicle 515 parked in a charging slot 511 is completed, the parking lot control system 200 may transmit, to the charging control apparatus 100 of the first vehicle 515, information on a waiting parking space around the parking position of a second vehicle having a high priority as illustrated in FIG. 5B. Thus, the charging control apparatus 100 of the first vehicle 515 may move the first vehicle 515 to park in a waiting parking space 521 on the basis of the information received from the parking lot control system 200.

In addition, when the first vehicle 515 is moved and parked in the waiting parking space 521, the parking lot control system 200 may transmit information on an empty charging slot 535 to a second vehicle 531 that is waiting for charging as illustrated in FIG. 5C. Then, the charging control apparatus 100 of the second vehicle 531 may move the second vehicle 531 to park in the empty charging slot 535 on the basis of the information received from the parking lot control system 200. Here, when the second vehicle 531 has been parked in the charging slot 535, the charging control apparatus 100 of the second vehicle 531 may start wireless charging of the second vehicle 531.

Thereafter, the parking lot control system 200 may transmit information on an empty non-charging slot 541 to the first vehicle 515 as illustrated in FIG. 5D, the charging control apparatus 100 of the first vehicle 515 may move the first vehicle 515 which has been charged to park in the empty non-charging slot 541. Here, the charging control apparatus 100 of the first vehicle 515 which has been moved and parked in the non-charging slot may transmit information on completion of moving and parking to the user terminal 300 through communications, as shown in FIG. 5E.

The user terminal 300 may output moving and parking guidance information on a display screen on the basis of the information on completion of moving and parking received from the charging control apparatus 100 of the first vehicle. Here, the moving and parking guidance information may be output on the display screen of the user terminal 300 as illustrated in FIG. 6.

Referring to FIG. 6, a moving and parking guidance screen 610 may include information 611 on the state of charge of the vehicle, for example, information on charge amount and driving range (travelable distance). In addition, the moving and parking guidance screen 610 may include information on the position of a vehicle 615 that has been moved and parked.

Therefore, the user may be notified that the vehicle 615 has been parked in a ninth parking space of a first basement level (B1) on the basis of the vehicle position information on the moving and parking guidance screen 610 illustrated in FIG. 6.

FIGS. 7A through 7C illustrate a sequence of operations in moving and parking a charging vehicle and a waiting vehicle when the charging of two vehicles is completed simultaneously, according to an exemplary embodiment of the present disclosure.

As illustrated in FIG. 7A, when a first vehicle 715 puked in a first charging slot 711 and a second vehicle 725 parked in a second charging slot 721 have been charged simultaneously, the parking lot control system 200 may check charging start time of the first vehicle 715 and the second vehicle 725.

As illustrated in FIG. 7B, the parking lot control system 200 may control the first vehicle 715 which first starts charging to move and park first. Here, the parking lot control system 200 may control the first vehicle 715 parked in the first charging slot 711 and a third vehicle 735 having the highest priority to move and park on the basis of the operations illustrated in FIGS. 5A through 5E.

Thereafter, as illustrated in FIG. 7C, the parking lot control system 200 may control the second vehicle 725 which starts charging later to move and park. Here, the parking lot control system 200 may control the second vehicle 725 parked in the second charging slot 721 and a fourth vehicle 745 having a next highest priority after the third vehicle to move and park on the basis of the operations illustrated in FIGS. 5A through 5E.

FIGS. 8A through 8C illustrate a sequence of operations in moving and parking a vehicle parked in a standard charging slot and a vehicle parked in a quick charging slot when the charging of the vehicles is completed simultaneously, according to an exemplary embodiment of the present disclosure.

As illustrated in FIG. 8A, when a first vehicle 815 parked in a standard charging slot 811 and a second vehicle 825 parked in a quick charging slot 821 have been charged simultaneously, the first vehicle 815 may be slowly charged to 100% and the second vehicle 825 may be quickly charged to about 90%.

Therefore, the parking lot control system 200 may control the first vehicle 815 which is fully charged to 100% to move and park first. Here, since there is an empty non-charging slot 831 as illustrated in FIG. 8B, the parking lot control system 200 may guide the first vehicle 815 into the empty non-charging slot 831, without providing information on waiting parking space.

If there is no empty non-charging slot, the parking lot control system 200 may control the first vehicle 815 and a waiting vehicle having the highest priority to move and park.

Since the second vehicle 825 parked in the quick charging slot 821 is not fully charged, the parking lot control system 200 may control the second vehicle 825 to move and park into the standard charging slot 811 which is open. Therefore, the charging control apparatus 100 of the second vehicle 825 may park the second vehicle 825 in the standard charging slot 811 and control wireless charging of the second vehicle 825, thereby allowing the second vehicle 825 to be slowly charged to 100%.

Although not shown, after the second vehicle 825 has been moved and parked in the standard charging slot 811, the parking lot control system 200 may control the waiting vehicle having the highest priority to move and park in a quick charging slot.

As illustrated in FIGS. 9A and 9B, the parking lot control system 200 may check the states of charge of vehicles which are being charged in standard charging slots, and allow any one of the vehicles to move and park in an empty quick charging slot according to the states of charge.

Referring to FIG. 9A, when quick charging of a first vehicle 915 parked in a quick charging slot 911 is completed, the parking lot control system 200 may transmit information on an empty non-charging slot 921 to the charging control apparatus 100 of the first vehicle 915. Here, the charging control apparatus 100 of the first vehicle 915 may move the first vehicle 915 to park in the empty non-charging slot 921 on the basis of the information received from the parking lot control system 200.

Thereafter, the parking lot control system 200 may check the states of charge of vehicles parked in standard charging slots. The parking lot control system 200 may determine which vehicle is to be moved and parked into a quick charging slot on the basis of priority of entry into the standard charging slots, charge amount, and/or remaining charging time, excepting cases where the charge amount of a vehicle is greater than or equal to a predetermined level (%) or the automatic moving and parking function of a vehicle is not activated.

Here, as illustrated in FIG. 9B, the parking lot control system may determine a third vehicle 935 having a charge amount of 50% and a remaining charging time of 3 hours as a target to be moved and parked, and control the third vehicle 935 to move and park into the quick charging slot 911.

Therefore, after the third vehicle 935 has been moved and parked in the quick charging slot 911, the charging control apparatus 100 of the third vehicle 935 may control quick charging of the third vehicle 935.

Although not shown, after the third vehicle 935 has been moved and parked in the quick charging slot 911, the parking lot control system 200 may control a waiting vehicle having the highest priority to move and park in an empty standard charging slot.

FIG. 10 illustrates the configuration of a computing system by which a method according to an exemplary embodiment of the present disclosure is executed.
